To help you better understand your machinery, here are definitions for some common parts and their functions:
The core component of a hydraulic system, generating the hydraulic pressure required to operate various functions. It is typically located in the engine compartment. For example, the Sandvik DD421 main pump.
The ground-engaging components of a tracked vehicle, providing mobility and support. It is located at the base of the machine. For example, the Atlas Copco PowerROC D55 undercarriage.
A moving component within a hydraulic rock drill that creates the impact energy to break rock. It is found inside the drill's hammer mechanism. For example, the Epiroc Boomer L2C percussion piston.
A gearbox at the end of a drivetrain that reduces speed and increases torque to power the tracks or wheels. It is located at the end of the machine's undercarriage. For example, the Sandvik DD422i final drive.
A wheel that guides the track and supports the machine's weight, helping to distribute the load evenly. It is located on the underside of the track frame. For example, the Atlas Copco PowerROC T35 track roller.
The pointed tool at the end of a hydraulic breaker used for demolition and rock breaking. It is located at the end of the breaker attachment. For example, the Epiroc HB 4700 chisel.
A hydraulic motor that rotates the machine's upper structure. It is located in the machine's swing mechanism. For example, the Sandvik DT1130 swing motor.
A system of gears that transmits power from the engine to the wheels or tracks, controlling speed and direction. It is located in the machine's drivetrain. For example, the Atlas Copco ST710 transmission.
An internal combustion engine that uses compression to ignite fuel, powering the machine. It is located in the engine bay. For example, the Epiroc Boomer 282 diesel engine.
A linear actuator that converts hydraulic energy into mechanical force and movement. It is located at various points on the machine, such as the boom or bucket. For example, the Sandvik Ranger DX800 hydraulic cylinder.
